One of the following ion is used for the activation of pty-alin and maltase

Options

A. Sodium ions
B. Potassium ions
C. Chloride ions
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Enzymes**: The question mentions two enzymes: ptyalin (also known as salivary amylase) and maltase. Both of these enzymes are involved in the digestion of carbohydrates.

2. **Function of the Enzymes**:
- **Ptyalin**: This enzyme is responsible for breaking down starches into simpler sugars (maltose).
- **Maltase**: This enzyme further breaks down maltose into glucose, which is a simple sugar that can be easily absorbed by the body.

3. **Role of Ions in Enzyme Activation**: Enzymes often require specific ions to become active. These ions can help in the proper functioning of the enzyme by stabilizing its structure or participating in the reaction.

4. **Identifying the Required Ion**: The question asks for the specific ion that activates both ptyalin and maltase. Research and biological knowledge indicate that chloride ions (Cl-) play a crucial role in the activation of these enzymes.

5. **Conclusion**: Therefore, the ion that is used for the activation of ptyalin and maltase is the chloride ion.

**Final Answer**: The ion used for the activation of ptyalin and maltase is the chloride ion (Cl-).
